15 Claims.

This invention relates to improvements in discharging formed glassarticles from the forming mechanism. More particularly, it relates tothe discharging of hollow blown glass articles from a rotary blowingmachine.

The object of the invention is to discharge the blown glass articlesfrom the blow mold in such a way as not to interfere with the associatedglass forming devices, and with a minimum of danger of injury to theblown articles. More specifically, the object is to properly deliverblown articles from a blowing machine wherein the completed article isdischarged from a blow mold past a parison mold. A further object of theinvention is to provide a receiving trough which will receive formedarticles from a continuously rotating forming machine and deliver thesame to a stationary chute, the receiving end of the trough moving withthe forming apparatus during the receiving operation. Other objects anddetails of the invention will appear as the description proceeds.

In the accompanying drawings forming a part of this specification,

Fig. 1 is a plan view of apparatus showing one embodiment of theinvention;

Fig. 2 is a vertical section of a portion of the apparatus approximatelyalong line 22 of Fig. 1;

Fig. 3 is a vertical section of a portion of the apparatus approximatelyalong the line 3-3 of Fig. 1;

Fig. 4 is a detailed section on the line 4-4 of Fig. 2.

In the combination-shown in the drawings, the forming apparatus ismounted upon a central column In. Rotating about this column there is alower spider II and an upper spider I2 connected at the outer circle ofthe apparatus by means of vertical columns l3. A parison carrier I4 ismounted upon each pair of adjacent columns. There are a plurality ofsimilar forming devices mounted in an annular series about the centralcolumn, as will be readily understood, only one of these devices beingshown in the drawings, the other devices being exactly similar inconstruction, as will be readily understood.

Mounted upon the lower spider ll there is a mold carrier slide [5.Downward and outward 50 from the mold carrier slide there projects abracket IS on the outer end of which there is mounted a mold bottomsupport I! pivoted on the bracket at I8. A mold bottom'l9 is mountedupon the .bottom support l8 by means of an adjustable 55 connectionzll.In this way'tbe bottom maybe readily adjusted vertically to accommodatemolds of different lengths for molding bottles or the like of differentsizes.

Mold sides 2| are mounted in the usual way upon arms 22 which arepivoted at 23 upon the mold slide. The slide is provided with a roller24 connected in the usual manner to the mold operating arms to open andclose the mold. The roller is actuated at proper times by a cam 25mounted upon the central column. The mold 10 carrier slide also carriesa cam roller 26 which is operated by a cam 21 on the central column tomove the slide inward and outward as desired.

Mold bottom support I1 is provided with seg- 15 mental gears 30 whichmesh with segmental gears 3| on .a lever 32 which is fulcrumed at 33upon mold bottom bracket IS. A spring 34 is attached to lever 32 and tobracket l6 so as to normally hold the bottom in the upright posi- 20tion, in which it is shown in the drawings.

A rod 35 is pivoted to the bottom oflever 32 and slides throughanopening in a lug 36 which is pivoted in the top of a lever 31. Lever31 is fulcrumed at 38 in a gear wheel 39 connected 25 with the bottomspider. A cam 40 is mounted upon the central column beneath gear wheel39 and engages a cam roller 4| on the lower end of lever 31. An abutment42 is mounted upon rod 35 and is engaged by lug 36 when the upper end oflever 31 is moved outward.

Pivot I8 is arranged at an angle so as to discharge a formed bottlebetween a parison 43, suspended from parison carrier l4, and the ad- 35jacent connecting column l3. Also, it preferably l discharges the bottlein a direction that slants backward with respect to the movement of themold in its revolution about the central column. Above bottom I9 thereis arranged a blow head, not shown, which may be actuated by anysuitable means not shown for cooperation with the blow mold when thesides are closed about the bottom.

A motor 45 is mounted on one side of the base 45 46 which supportscolumn III. A shaft 41 is mounted in a bracket 48, also mounted uponbase 46. Shaft 4'! is driven by a sprocket chain 49, which engagesasprocket wheel 50 on the motor shaft and a sprocket wheel 5| on shaft41. One 50 end of shaft 41 is provided with a worm 52 which engages aworm wheel 53 on an upright shaft 54 which carriesat its upper end agear 55 meshing with gear wheel 39. During the normal oporation of theapparatus. motor .45 was .congs ed on the under side of carrier 59,engage astationary track 66 and compel the trough to rotate in aninclined plane.

Mounted at one side of the .path'of the troughs, as shown in Fig. 1,there is a chute 61 adapted to discharge the blown article to anysuitable receiving means.

It will be readily observed that if a bottle 69 reaches the dischargeend of the trough prior to the registering ofthe discharge end of thetrough with the receiving end of the chute, the end of the bottle willride against plate 68 until it reaches the chute, whereupon it will bedischarged into the chute. As will appear from Fig. 1, the portion 10 ofcam 40 is so located that the mold bottom is tilted to discharge thebottle into the upper end of the trough while the lower end of thetrough is directed against abutment plate 68. Preferably the action istimed so that the bottle will slide down the trough and reach thedischarge end at about the time the discharge end registers with thechute; but the use of abutment plate 68 provides for some leeway in theadjustment so that the timing does not need to be as accurate as itwould otherwise have to be, and also accidental variations from theusual speed of movement of the discharged article will be taken care ofautomatically.

The operation of the device'will be evident from the foregoingdescription, but for convenience may be summarized as follows:

It will be readily understood that any suitable parison-formingapparatus is mounted upon the turret at a point lower than the blowmold. Suitable means may be provided for raising and lowering parisoncarrier I4 upon the columns I3 so as to raise the formed parison 43 fromits forming position to a position on a level with the blow mold. At theproper time, cams 25 and 21 move the blow mold slide outward and closethe blow mold about the suspended parison 43. Later, the blow mold slideis moved inward and 5 the article may be either blown or sustained inblown shape by blow head 44. For purposes of speeding up the operationof the mechanism it is preferable to retain the bottle on bottom l9until the succeeding parison has been formed and 50 raised to theposition in which it is shown in the drawings. T-hereupon cam portion 10of cam 40 operates lever 31 to move its upper end outwardly so that lug36 contacts abutment 42 on rod 35 and forces outward the lower end oflever 32 against the tension of spring 34. By means of the-segmentalgear connections, this tilts the mold-bottom outwardly about inclinedpivot I8 and discharges'the bottle outward between blank 43 and thefollowing column l3. The movement .70 of trough carrier 59 issynchronized with the movement of the turret so that the receiving endof the trough enters between column 9 l3 and parison 43 in position toreceive the bottle when it-isdischarged; A's'w'illbe seen, thecushioning q blockis in the receiving end of the trough chan- Extendingfrom .one side of the receiving end of chute 61 there is an abutment 0plate 68.

nel nearest to the parison, and the bottle is tilt ed onto thecushioning block, which may be made of wood or the like. The bottle thenslides down the trough and is discharged into chute 61, as previouslydescribed. The trough is rotated so that the other end of the troughmember brings the receiving end of the other trough channel intoposition to receive the bottle from the next succeeding blow mold.

The support 66 may be shaped in any desired Way so that the troughcarrier may be rotated in the same way in which it would move about afixed inclined axis, or the surface of member 66 may be, and preferablyis, flattened at the highest and lowest-points, so as to give atemporary dwell atsubstantially the same inclination while receiving anddischarging the article.

It will be readily seen that the rotating receiving trough substantiallyas described might be employed with widely differing glass-formingapparatuasince it could be synchronized with any suitable rotatingforming device, but it is particularly adapted for use with apparatuswhere it'is necessary or desirable to receive the discharged article ata point inside of the exterior circle of the glass forming apparatus. Itwill be seen also that the feature of discharging the blown article atan angle so as to avoid the parison located directly outward therefrommight be utilized. with varying'receiving devices. It will also beunderstoodthat other apparatus might be employed for inserting thereceiving end of a discharge trough between members on the outer circleof a lass-forming machine in order to receive. the finished article at apoint within said outer circle. Therefore, while the various features ofthe apparatus as shown and described cooperate witheachother toaccomplish a very desirable and efiicient means of delivering the blownarticle, it will be readily understood that various modifications may bemade, and that some of the features may be used separately withoutsacrificing all of the advantages of the invention, and thereforedepartures may be made, from the construction shown and described,within the 'scopeyof the appended claims.
